iiiornizi, Vfinvo invented Lnprovements in Strokerlod Qetohes, of wliiohthe tollowing is sy specification.

y invention rehtes primarily to e eaten 'ich is eonneeted to the denrerj-.fv pipe of :in oil well and the object eet is to provide s estabwhich is easily ielrly ettsolied 'to the delivery pipe op; of suolrerrods in e top section or' the noted :troni the string or while isoonneeted. to the string.

J' forming e part oi: this l is :i side elevation ot L itioned in thetop oit y pipe, which pipe y, notion with p rtion oi? s'liolier rod heldesiiglit thereby. Figure zi side elevation of the catch de from the pipewith the top member i L o inoperative position. Figis s, top plan of theports shown in @nre @ent oit t terrine; to the dii'ewings,l 5 is esection fl" of the delivery pipe of en oil well end 6 is e Couplingmember by whioh two sections Y ed together. eoinprises e body member 7which. bes o. reduced lower end 8 which is ezternelly threaded end whenpositioned for use screws into coupling 6. Extending centrally throughthe body member is e bore 9 which is large enough for the passagetherethrough oit coupling; members oft the smoker roth one of which l0is shown Figure l coupling sections l1 of the seeker rod together.litlember l0 hes en internally screw threaded bore into which the endsof seotions ll screw and has flattened portions shown et l2 for thereception of tool. The ends of seotions 11 are squared at 13 also torthe reception oit e tool when the ports are to be i'oinod` or seperated..ll/leL bei' hes eers lllin which the handle l5 oi1 the top member i6 ismounted; by bolt l? which passes throng-h tbe eers ond handle. li/ember7 hss s slot 18 therein which is oi' less width than bore 9, beingrpreferably of e width to yinst permit the body of the seotions o??'thro-19h.

:ober it@ e, slot l@ therein of the siiolrer rod.

soolter-rod to pass there-v Seriall No. 313,553.

whioli is just large enough to permit the bodyto be turned beek on thebody portion Slot `19 terminates at the for edge oit bore 9 when thepertsere positionet for 1ese es shown in Figure l. Slot 18 is preferablydiagonal so that in raising or lowering the sucker rod it will be keptcentral in bore 9.

@poration Assuming now that e well is to be pulled, the elevator, notshown, is etteohed. to the top oit the seeker rod in the usuel welll-:nownmenner end the rod is elevated so that the Hirst sneller rodcoupling is et o distsnoe above the top oi the delivery pipe. Thevmember or the oetol'i is thrown beck ,ii-nd the bottom member is thenpassed onto the siro-'ker rod end is then straightened up end screwedinto the top of the delivery The top member is then turned onto the topmember which prevents the rod from going any further. The top sectioneen then be nnsorewed and positioned in the tower. The operation is thenrepeated until the rod is removed.

To lower e rod a. section thereoiC would be caught by the elevator andlowered into the pipe until the coupling caught on the oeteh. Theeleifetor would then be detached sind edited to ay second section whichwould then be positioned end screwed to the first section and bothraised so es to permit the top member of the catch to be thrown beekwhen both sections would be lowered.

After the coupling had passed through the bottom member, the top memberwould be thrown beek to position end would` eeteh the rod et the end andhold it and. the operation would be repeated with each section until therod was lowered. Other means con be used to detsohsbly secure the @etch`epon the delivery pipe. By dividing the lower member vertioelly theslit therein eonld be omitted.

lele-ving described my invention l claim:

i. A sucker-rod catch comprising e lower member adapted Yto bedeteebebly secured upon the top oit e well delivery pipe, seid memberhaving e central bore adapted for the passage therethrough of thecoupling members of the sucker-rod, en opper member hingedly connectedto seid lower mezn ber. seid upper member having e slot there inextending to the f ar edge of the bore of the lower member whenpositioned for use, said slot being vertical when positioned lor useVand of a less width than the diamter of the coupling members ofV thesucker-rod.

2. A sucker-rod catch comprising a lower member having a bore extendingtherethrough, saidy member having a reduced lower end externallythreaded and a slot extending to the bore; an upper member hingedlyeonneeted to the lower member said upper member having a slot extendingbeyond the bore of the lower member when positioned for use, the slot inthe upper member being of less width than the coupling member of thesucker-rod and the bore of the lower member being of a size to permitthe sucker-rod couplings to pass therethrough.

In witness that I claim the foregoing I have hereunto subscribed my namethis 11th day of January 1923.
